Abstract: The flowmeter has a measuring pipe for the flow medium and at least one ultrasonic transmission/reception device, with a reflector within the measuring pipe for the ultrasonic waves directed through the flow medium. The formation of harmonic waves at the reflector surface (10) is effected by using an incidence angle relative to the surface normal which is greater than the Rayleigh angle and/or by using a reflector with material characteristics providing a high Rayleigh velocity. The reflector may be made of ceramics, e.g. aluminium oxide.

Abstract: In a non-stop stack changing device, remaining-stack bars are pulled from the stack area one by one and out-of-line in relation to each other. To this end, a pull/push drive is provided, which makes it possible to push the remaining-stack bars simultaneously into the grooves of a pallet carrying a sheet stack. Furthermore, the pull/push drive makes it possible to pull the remaining-stack bars in pairs from inside outwards out of the stack area. In addition, the remaining-stack bars can be pulled in a first and second sequence in accordance with this model. An individual motor drive is provided for this purpose, which operates interlockingly on each individual remaining-stack bar.

Abstract: A modular insert for curb-inlet storm drains creates a composite collection system for trash and for oil or other hydrocarbons and related chemicals. A hopper contains a multitude of irregular, macroscopic fragments of a hydrophobic, compliant, oil-absorbent, copolymer material having high surface area. Preferably, the material is formed with a binder in a novel extrusion process. The fragments absorb and retain permanently a high quantity of oil and other chemicals passing through the hopper, while permitting a high water flow-through rate. The fragments are held in place by a removable bottom plate, which allows replacement of the filtering fragments, and an internal basket. Trash and debris are collected in the internal basket. The hopper is configured to be suspended in a storm drain adjacent to a curb inlet on a bracket and can be installed or serviced through a conventional manhole entry. The hopper has a side cutout that permit lateral overflow from one of the modular units to an adjacent one.

Abstract: A pairing of two profiled sections (10, 10a), especially extruded aluminium alloy profiled sections, with two interspaced flange walls (15), whereby ribbed connecting pieces (30) extending from the flange walls (15) of one of the profiled sections (10a) are respectively inserted into a recess (24a) of the other profiled section (10) before the profiled sections (10, 10a) are soldered to each other at said connecting pieces (30). The connecting pieces (30) are centered on the walls of the recesses, whereby the offset between the adjacent surfaces (12, 12a) of the profiled sections and overlapping are kept to a minimum. Since the radius of the circular cross-sectional contour of the grooved recess (24a) is greater than the radius of the corresponding circular contour of the connecting piece (30), the welding stresses result in positive centering without any play. The connecting pieces (30) have a respective longitudinal groove (32) that is open towards the outer surface (12a) of the profiled section and which is partially covered by the nose (13) of the other profiled section (10). The front face of the nose (13) forms a channel area in conjunction with a sloping surface associated with the longitudinal groove (32), whereby said channel area tapers inwards towards the longitudinal groove (32) and is connected to said groove by a slit (38).
